Katz, Orange, N..I., assignor to Super Sagless Spring Corp, Bayonne, NJ, a corporation of New Jersey Filed Mar. 18, 1965, Ser. No. 440,844 18 Claims. (Cl. -13) This invention relates to beds. It is particularly related to a collapsible loose pillow back or fixed pillow back sofa bed of the four section type on which people sleep lengthwise of the bed, with head or feet at the sofa frame.

An object of this invention is to provide in a sectional bed of the character described having a main spring controlled member pivoted to the chassis, a throw out member, and means to connect said main member and throw out member to sections of the bed, and means to pivot the throw out member on a movable pivot connected to the chassis.

A further object of this invention is to provide a bed of the character described in which the moving pivot is on a link pivoted to the chassis.

Still another object of this invention is to provide a bed of the character described in which said link is part of a four-bar linkage of which the chassis comprises a fixed link and of which a part of the main member comprises a pivoted link.

Still another object of this invention is to provide a bed of the character described in which the link which carries the movable pivot projects upwardly and the throw out member pivoted to said link on said movable pivot projects upwardly therefrom, when the bed is fully collapsed, and said bed having means under the control of the main member, to swing said link forwardly to move the movable pivot forwardly as the bed is opened up from fully collapsed condition, to swing the throw out member rearwardly and downwardly relative to said movable pivot, whereby, a longer throw out member may be used.

In accordance with the invention, when the rear throw out member swings rearwardly toward the back of the sofa frame, the moving pivot moves forwardly to keep the throw out member from going too far back, so that a narrower back may be used. If the pivot point for the rear throw out member were fixed and did not move forwardly as the bed began to open up, the throw out member would reach back too far and hence would require a much thicker sofa back, hence resulting in a much bigger sofa.

In the fully collapsed position of the bed, the bed comprises a head section which extends vertically at the rear of the sofa frame back, a rear relatively long intermediate section pivoted to the lower end of the vertical back section and extending horizontally and forwardly therefrom, a front relatively short intermediate section pivoted to the front end of said rear intermediate section and extending vertically upwardly therefrom and located just inside the front of the sofa frame, and a foot or front section pivoted to the upper end of said vertical front short intermediate section and extending horizontally rearwardly over the rear intermediate section in spaced relation thereto. In such collapsed position of the bed, the bed mattress has a rear vertical portion in front of the vertical head section and rearwardly of the outer end of the foot section, a horizontal portion extending forwardly from the lower end of said rear vertical portion and lying on said rear horizontal intermediate section, a folded back portion extending from the front end of said horizontal portion and disposed at the short front vertical intermediate section, and a horizontal portion extending rearwardly from said folded back portion and lying on the first horizontal portion and beneath said foot section.

It is hence another object of this invention to provide in a bed of the character described, means to hold the rear vertical head section of the bed from falling against the back of the sofa frame, when the bed is fully collapsed and at the same time restrains the rear vertical portion of the link fabric (which provides a platform for the mattress when the bed is opened up) from being bulged rearwardly by the rear vertical portion of the mattress, and to hence prevent the link fabric from tearing the sofa covering at the back of the sofa.

It is hence also another object of this invention to provide a bed of the character described having means to hold said rear vertical section of the bed, when the bed is fully collapsed.

Still another object of this invention is to provide in a bed of the character described, means to support the rear or head section of the bed when said section has been swung from its rear vertical position to its lowered, substantially horizontal position, when the bed is moved from fully collapsed position to partially opened up position and before said head section begins to be raised upwardly, and also as the bed is being collapsed and said rear or head section is in its lowered bottom position.

A still further object of this invention is to provide a bed of the character described having means to move part of the mechanism which connects the rear throw out member and the main actuating member to bed sections, downwardly and then upwardly at the back of the sofa frame, during the collapsing action of the bed.

A still further objection of this invention is to provide a strong, rugged and durable sofa bed of the character described, which shall be relatively inexpensive to manufacture, easy to manipulate, comfortable in use, and which shall yet be practical and efficient to a high degree.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the construction hereinafter described, and of which the scope of invention will be indicated in the following claims.

2 FIG. 8 is a sectional view taken on line 8-8 of FIG.

; and

FIG. 9 is a side view of the slider bar and stop link apart from the bed.

Referring now to the drawings in detail, the present invention comprises a sofa frame F and a collapsible bed B mounted thereon. Frame F comprises a back wall 10, a pair of side walls 11 connected thereto, and a front board 12, interconnecting the lower portions of the side walls 11. Suitable legs 13 are provided to support the frame F. It is to be understood that the frame F may be upholstered, and will include loose seat cushions and either loose back cushions or a back cushion fixed to the front surface of the back wall 10, which cushions and upholstering is not shown for the sake of clarity. The frame F is of conventional construction and is shown in phantom.

In the following description of the bed B, the drawings show only one side of the bed and the mechanism on the other side is identical but symmetrically disposed.

The bed B is mounted on L shaped chassis member comprising a plate 15a formed with an offset flange 15b. Plate 15 is fixed to the inside surface of side wall 11, and flange 15b is fixed to the front board 12 by any suitable means. Pivotally mounted to the rear end of chassis plate 15a, in spaced relation to back wall 10, as by pin 16, is moving pivot link 17. Chassis 15 is provided with an inwardly protruding depressed portion 18 adjacent the forward end thereof, through which passes a pivot 19 on which are mounted main drive lever 21 and spring mounting tie member 22. Lever 21 and member 22 are also fixed together by a pair of rivets or pins 23. Lever 21 and member 22 are thereby firmly fixed together. Member 22 is of L shape, having a long arm 22a and a short arm 22b. Long arm 22a is provided with an opening 24 adjacent its outer end which receives one end of coil spring 25 therein. Mounted on chassis 15 by suitable pins or rivets 26 in spaced relation to pin 19, is spring anchor angle block 27. Fixed to the rearwardly facing surface of inwardly extending leg 27a of angle 27, is a nut 28. Passing through nut 28 and a suitable registering opening in leg 27a is the threaded portion of a hook or eye bolt 29 which adjustably, tension wise, anchors the opposite end of spring 25.

Pivoted to the outer end of short arm 22b of member 22, as by pivot pin 30, is the free end of the short arm of an L shaped connecting link 31. The free end of the long arm of link 31 is pivoted to an intermediate portion of moving pivot link 17 as by pivot pin 32. The bend in link 31 is reenforced by lengthening means 33 to insure the rigidity of link 31. Fixed to the rear surface of the inwardly extending portion of chassis 15 is a cross angle iron 34 which extends the width of the bed to the corresponding portion of the chassis 15 on the other side thereof. Angle iron 34 serves to strengthen the entire structure and as a locating stop for the bed in the collapsed position which will be described hereinafter. Two dog-leg slots 35 are provided in the upper edge of chassis 15.

The remaining portions of the bed B are mounted only on the structure thus far described.

Pivoted to the free end of the link 17, as on pivot pin 36 is rear throw out link 37. As is shown most clearly in FIG. 1, the rear throw out link 37 is of a composite shape and comprises a first leg 37a having its outer end pivoted on pin 36, a second leg 37b perpendicular to leg 37:: at one end, and a third leg 37c extending from the other end of leg 37b, to the opposite side as leg 37a extends, at an acute angle to the centerline of leg 37b.

Pivoted to the free end of leg 370, as by pivot pin 38, is :a control link 39. Link 39 is of a composite shape and comprises a first leg 39a having its outer end pivoted on pin 38, a second leg 39b at an acute angle to the centerline of leg 39a, and a third leg 39c extending from the other end of leg 39b to the opposite side as leg 39a extends, at a large acute angle to the centerline of leg 39b.

Fixed to leg 38a of link 37, adjacent the juncture with leg 37b, is a cross bar 40, which extends the width of the bed and is joined to link 37 at a corresponding spot on the link 37 on the other side of the bed. Similarly, a cross bar 41 interconnects the links 39 on opposite sides of the bed B, at the corresponding junctures of the legs 39a and 39b. The functions of the cross bars 40 and 41 will be explained hereinafter.

The free end of leg 390 of control link 39 is pivotally connected, by common pivot pin 42, to join the pivotal connection between the rear bed section 43 and the rear 4 intermediate bed section 44. Pivoted to leg 390 of link 39, as by pivot pin 45, between the free end thereof and the juncture of legs 39c and 39b, is one end of a reclining link 46. Link 46 and its function will be described hereinafter.

Pivoted to link 37 at the juncture of legs 37b and 370 thereof, on pivot pin 47, is one end of a substantially straight control link 48. The other end of link 48 is pivoted by pivot pin 49 to one end of a control link 50. Pivoted to control link 50, in spaced relation to the other end thereof, on pivot pin 51, is the other end of the main drive lever 21. Said other end of link 50 is pivoted on pivot pin 52 to one arm of a bell crank lever 53. Bell crank lever 53 is pivoted to the rear intermediate bed section 44 on pivot pin 54.

The bed sections themselves are of well known type, and are formed of angle iron side members which have one flange extending upwardly and the other flange extending inwardly when the bed is opened. The rear ends of the angle irons forming the rear bed section 43 are joined by an end bar 55 to complete the rear end of the bed frame. A link fabric 56 is supported in the bed frame by suitable springs 57 which are attached to the inwardly extending flanges of the bed section side angle irons and to the bed frame end bars. The link fabric 56 serves to support the mattress M, and is conventional.

Rear bed section 43 carries a fixed pin 58 in the upwardly extending flange of the angle iron side members intermediate the ends thereof. Pin 58 passes through a slot 59 formed in link 46. Pivotally mounted on pin 58, externally of link 46 is a butterfly member 60 (FIG. 6). Member 60 is of rectangular shape having two V notches cut into the two short sides thereof, thereby producing four triangular points or portions 60a, 60b, 60c and 60d. An externally extending flange 61 is provided along one side of link 46. An externally extending flange 62 is provided at the juncture of the top edge and the side opposite flange 61 of link 46, but smaller than the distance between flanges 61 and 62 measured along the length of link 46; and the width of member 60 is smaller than the width of member 46, but larger than the distance between the flanges 61 and 62 measured along the width of link 46. The operation of this mechanism will be explained hereinafter.

A stop link 63 (FIG. 5) has one end pivoted at 64 to the inside surface of the upwardly extending flange of the side angle iron of the rear bed section 43. The other end of said stop link 63 is pivoted to a portion of the open position locking mechanism which will be described hereinafter.

Pivoted to the free end of the other leg of hell crank 53 at common pivot 64 is a rear leg operating link 65. Pivoted to the front end of rear intermediate bed section 44 is the rear end of front intermediate bed section 66 at common pivot 67. A rear leg 68 is also pivoted on common pivot 67. A cross bar 68a runs across the bed to join the rear legs 68. Rear leg 68 includes an upper flange 69, to which a leg portion 70 is fixed. Flange 69 includes common pivot 67 at the upper end thereof when the bed is in the extended position, and includes a pivot 71 spaced below and to the rear of common pivot 67 to which the other end of rear leg operating link 65 is pivoted.

The vertical outer flange of the side angle irons of intermediate bed section 44 is provided with a plurality of slots, 72, 73, 74, 75. On the other side of the bed slot 75 will be in the position of slot 72, and the other slots are reversed accordingly. Slidingly mounted in slot 74, is a common pivot pin 76. A control link 77 has one end pivoted at 76, and has a second end which is provided with a slot 78, which slot 78 is slidably and pivotally mounted at common pivot 64. Mounted on common pivot 76, on the same side of slot 74 as link 77 is mounted, is one end of a control link 79. The other end of link 79 is pivoted, at pivot 80, to the intermediate, external flange of the angle iron of the front intermediate bed section 66.

Fixed to common sliding pivot 76, at the side of slot 74 opposite the side on which links 77 and 79 are mounted, is one end of a slider bar 81. The other end of slider bar 81 is mounted by pin 82 in slot 72. Pin 82 extends outwardly of slot 72 for a purpose to be described hereinafter. Slider bar 81 is provided with a slot 83 (FIG. 5), adjacent the rear end thereof, that is, adjacent pin 82. The other end of stop link 63 is slidably and pivotally mounted on pin 84 which is received in slot 83. Fixed to control link 50, as by rivets 85, is a locking plate 86. Pin 84 extends through slot 73.

As shown in FIGS. 2, 5 and 8, locking plate 86 comprises a relatively wide upper flange 87, a relatively narrow lower flange 88, an outer, central portion 89, and upper and lower sloped portions 90 and 91, interconnecting the upper and lower flanges to the central portion respectively. Plate 86 is provided with a slot 92 of irregular shape. Slot 92 has a bottom edge which extends along the line of juncture of lower flange 88 and sloped portion 91. Slot 92 includes a rear tapered wall extending from the bottom wall to a top wall. The top wall is longer than the bottom wall and is closer to upper sloped portion 90 than to lower sloped portion 92, and if formed in central portion 89.. Extending upwardly from the other end of the bottom wall is a short sloped wall. An intermediary ledge 93 extends from the top of the short sloped wall. The end of the ledge 93 is joined by a curved wall to the other end of the top wall. The ledge 93 is formed in the central portion 89 closely adjacent the juncture of portions 89 and 91. The operation of locking plate 86 will be explained hereinafter.

Pivoted to control link 79, as at 94, is one end of a control link 95. Pivoted to the other end of link 95, as at 96, is one end of a control link 97. Pivoted to link 97, as at 98, adjacent the center of link 97, is one end of a control link 99. The other end of the link 99 is pivoted at 100 to the front intermediate bed section 66 at approximately the center thereof. Pivoted to link 97, as at 101, is one end of front leg operating link 102. The other end of link 97 is pivoted, as at 103, to the front bed section 104. The other end of link 102 is pivoted, as at 105, to the upstanding flange 106, of the front leg 107. The front leg 107 is pivoted to the front bed section 104 at a point 108 spaced below and forwardly of pivot 105, when the bed is in open condition. A cross angle iron 115 extends across the bed and joins the bottoms of front legs 107, forms a floor contacting bar and may serve as a gripping bar to aid in opening the bed. The rear end of the front bed section 104 is pivoted to the front end of the front intermediate bed section 66 by pivot pin 109.

A cross member 110 is provided, which connects the front ends of the side angle irons of the front intermediate bed section 66, at the undersides thereof, when the bed is in the open condition. An L shaped brace and locating bracket 111 has the free end of its long leg fixed to cross member 110 as at 112. The other end of its long leg, adjacent the bend forming the legs, is fixed to the horizontal flange of the side angle irons of the front intermediate bed section 66 as at 113. The short leg 114 extends downwardly and serves as a locating stop for the bed in folded condition by resting against cross angle iron 34 as shown in FIG. 1.

In FIG. 7 the position of the mattress is diagrammatically shown within the bed when it is in the folded condition, FIG. 1. The cross bar 40, linking the rear throw out links 37 is positioned against the front face of the mattress M, and holds the mattress againstthe vertical disposed rear bed section 43. The cross bar 41, linking the control link 39, rests against the rear or bottom face of the rear bed section 43 and supports said bed section in vertical position. The mattress M rests directly on the link fabric 56 of the bed B.

6 Operation On unfolding or setting up the bed B, the mechanism passes successively through the positions of FIGS. 1, 2, 3 and 4, FIG. 4 being the fully opened position.

During the first phase of the opening cycle, as the bed B is moved from the FIG. 1 to the FIG. 2 position, main drive lever 21 rotates in a clockwise direction on its pivot pin 19, being assisted in this motion 'by the pull of spring 25 acting on long arm 22a of member 22 which is fixed to lever 21. This motion causes connecting link 31 to move rearwardly which causes moving pivot link 17 to rotate in a clockwise direction about pivot pin 16. As this is happening, rear throw-out link 37 is rotating in a counter-clockwise direction about the moving pivot 36, thereby, acting through the links 48 and 39, moving the still folded front and front and rear intermediate bed sections upwardly and forwardly so that said sections, and the rear leg 68 will clear the front board 12. By using the moving pivot link 17, controlled by the motion of the main drive lever 21, the present invention can use a longer rear throw-out link 37 than was heretofore possible, while at the same time not requiring an excessively thick back wall which would be otherwise necessary to allow the throw-out link to swing rearwardly.

In the FIG. 2 position of the bed, the stabilizer bar 41 engages beneath the rear bed section to support the rear bed section as it is swung from its rear substantially vertical position to its lowered, substantially horizontal position, before the rear bed section begins to be raised upwardly.

In the second phase of the opening cycle, the bed B goes from the FIG. 2 to the FIG. 3 position. Main drive lever 21 continues to rotate clockwise and rear throw-out link 37 continues to rotate counter-clockwise. However, this continued motion causes only a negligible amount of continued motion of the moving pivot link 17 because the point of connection between short arm 22b of member 22 and connecting link 31 during this phase is moving substantially vertically, rather than substantially horizontally as during the first phase, and this vertical motion causes link 31 to simply pivot on pivot 32 rather than pull pivot 32 to drive link 17 as during the first phase. The continued motion of lever 21 and link 37, acting through control link 50, bell crank 53 and rear leg operating link 65, causes rear leg 18 to pivot in a counterclockwise direction about common pivot 67, to put the rear leg 68 into its unfolded supporting position shown in FIGS. 3 and 4, contacting the floor.

In the third and .last phase of the opening cycle, the bed B goes from the FIG. 3 to the fully extended FIG. 4 position. As the front intermediate bed section 66 goes from the folded vertical position to the opened or extended horizontal position, the control link 79 is pulled downwardly and forwardly to a horizontal position, which simultaneously causes the slider bar 81 to slide forwardly, and, acting through link 77 and common pivot '64, causes bell crank 53 to rotate slightly in a counter-clockwise direction. This motion causes pin 82 to move onto intermediary ledge 93 of slot 92 in locking plate 86, thereby locking all the operating mechanism to the rear of the rear leg 68 into the extended position. The locking plate 86 locks the relative position of control link 50 to rear intermediate bed section 44, and the locked structure also serves to support the rear of the bed B. Upon moving the front bed section 104 into the horizontal forwardly extending FIG. 4 position to complete the opening cycle, the links 95, 97 and 99, and the front leg operating link 102 rotate the front leg 107 in a counter-clockwise direction about its pivot 108 to put the front leg 107 into its supporting, floor contacting position shown in FIG. 4.

Of course, the closing cycle of the bed would be the above steps in reverse order.

When the bed is in the fully extended position, the rear bed section 43 can be rotated in a clockwise direction about common pivot 42 to a sitting-up or the so-called T.V. position. This position is shown in FIG. 6 and in dot-dash lines in FIG. 4. Before arriving at the FIG. 6 position, the butterfly member 60 had its two long, straight edges parallel to flange 61, slot 59 and the axis of link 46. To get to the supported sitting up position of FIG. 6, the user rotated rear bed section 43 clock- Wise and upwardly from its normal horizontal position, which motion caused rotation of link 46 clockwise about its pivot 45 on link 39, as well as causing stop link 63 to move upwardly and sliding forwardly on pivot 84 in slot 83 in slider bar 81, FIG. 5. It will be recalled that slider bar 81 has already been moved to its forward position. Slot 83 limits the clockwise rotation of rear bed section 43. When rear bed section 43 arrived at the limit of its upward motion, member 60 will be fully above flange 61 and free of said flange, and flange 62 will contact the inside edge of portion 60c, thereby tilting member 60 slightly off its previous vertical aligned position, and into the cocked position shown in phantom in FIG. 6. After reaching the limit and cocking member 60, the user releases the bed section 43 allowing it to fall downwardly in a counter-clockwise direction under his and its own weight. The inside edge of portion 60 will shortly thereafter contact the upper end of flange 61, and the inside edge of flange 61 will contact the inside edge of portion 60d and thereby bed section 43 is held in the sitting position. When it is desired to return rear bed section 43 to horizontal, it is again moved to its upper limit whereupon flange 62 will contact the outside edge of portion 60b, rotating member 60 into a substantially horizontal position, not shown. Upon thereafter releasing bed section 43, it will rotate downwardly and flange 61 will contact the outside edge of portion 60d, and will there-by rotate member 60 back to its original, aligned, vertical position. It can be seen that member 60 will turn 180 about its pivot 58 during each complete cycle, from horizontal to sitting and back to horizontalf It can also be seen that by appropriately locating slot 83 in slider bar 81, the upward rotation of rear bed section 43 is only possible when the front intermediate bed section 66 is in the opened or horizontal position.

It will thus be seen that there is provided a collapsible sofa bed in which the objects of the invention are achieved, and which is well adapted to meet the condi tions of practical use.
